Weight

Fix Recommendation

Configure AlmaLinux OS 9 to shut down by default upon audit failure (unless availability is an overriding concern).

Add or update the following line ("disk_full_action" can be set to "HALT" or "SINGLE" depending on configuration) in the "/etc/audit/auditd.conf" file:

disk_full_action = HALT

If availability has been determined to be more important, and this decision is documented with the information system security officer (ISSO), configure AlmaLinux OS 9 to notify system administration staff and ISSO staff in the event of an audit processing failure by setting the "disk_full_action" to "SYSLOG".

Check Contents

Verify that AlmaLinux OS 9 takes the appropriate action when the audit storage volume is full, with the following command:

$ grep disk_full_action /etc/audit/auditd.conf

disk_full_action = HALT

If the value of the "disk_full_action" option is not "SYSLOG", "SINGLE", or "HALT", is commented out, or is missing, this is a finding.
